what if someday when bitcoin has become the main payment instruments in the world. and how when the Internet network paralyzed. it means that we all can not perform various financial transactions? , is there any solution ?
Such a disaster has not occured so far.If it happens,then it would create a big problem not only to bitcoin users,but especially to all banks who carry out all of their transactions digitally.Then no one would be able to send and receive money to different parts of the world.In fact,total economy would collapse.So bankers have to worry much more than bitcoin users.
